PATENT OFFICE.

GAS-LIGHTING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 752,021, dated ruary 16, 1904..

Application filed October 19, 1901.

To all whom, it may concern.-

Be it known that I, PIERRE BABDOT, a citizen of the French Republic, residing at Lyons, France, have invented certain new and useful Improvements in Gas-Lighting Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for lighting gas-lights, and has for its object to provide an improved gas-lighting attachment especially designed for use in lighting incandescent burners in closed lamps, particularly in the closed lamps on outside lamp-posts.

With this object in view the invention consists in the improved constructiomarrangement, and combination of parts hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, Figure 1 illustrates a lamp provided with my invention, the parts being in their normal positions ready for operation. Fig. 2 illustrates the same during the operation of lighting. Fig. 3 is a sectional view of the two cocks, both keys of which are shown in the closed position. Fig. 4 is a sectional view of the same during the process of lighting. Fig. 5 is a sectional view of the double cock after the extinguishing of the lighting-jets. Fig. 6 shows the same when the incandescent burner is extinguished and when the auxiliary burner is alight. Fig. 7 shows a section of the cock which is especially made for the lighting lights or jets.

The lamp a, which is entirely closed, is provided with an incandescent burner 5, lightingpipe with jet 0, and an auxiliary burner d, with throttle-valve, both the lighting-jets and auxiliary burner being controlled by the two cocks e e in one block 6, into which the gas is entered through the branch pipe 6 The key'f of the cock e is operated by a lever g, while the other key it of the cock 6 is actuated by a lever 1 To proceed to the lighting of the incandescent burner b, a pole with torch Fig. 2, and

provided with a hook k is utilized, and by pulling on this pole the hook moves thelever Serial No. 79,270. (No model.)

9 from tht position shown in Fig. 3 to the position shown in Fig. 4. The torch j is thus brought to the orifice of a case Z, which protects a lighting-pipe m, Fig. 7, and the lighting-jets 0 being thus alight they transmit the fire to the burner I). The lighting-jets c being no longer required, the extinguishing thereof is eifected by further turning the key f of the cock by means of the hook-pole, which has not been removed from the lever g, the latter being now turned to the horizontal poposition indicated in Fig. 5. The incandescent burner 5 now burns alone, and this result has been obtained in about two seconds by causing-the lever g to describe a half-circle without noticeable stopping.

Should the incandescent burner be damaged and unlightable, use will be made of the auxiliary burner d, for the lighting of which the operation is as follows: The lever i, which controls the key it, will be brought to the position shown in Fig. 6 to open this key, and the lever will be operated to bring it from the position shown in Fig. 5 to the position shown in Fig. 6, closing the key f, taking care to make a slight stop at the vertical position of lever g to allow of the lighting-jets which transmit the light to the auxiliary burner d to be lighted, which burner (Z is alight by itself when both levers are in the position shown in Fig. 6.

In Fig. 7 is shown the small lighting-pipe m, which insures the lighting of the lightingjets, and a valve-screw 0?. permits of the reduction of the consumption of the gas when in the lighting position, thus avoiding explosions in the incandescent burner.

The block e is provided with a screw 0, which may be removed when it is desired to cleanse the opening communicating between the cooks e and c and with a screw 9, which controls the consumption of gas by the auxiliary burner.

The advantage of this device consists in permitting the rapid lighting without having to open any part of the lamp on the lamp-post and in insuring a continuous lighting by using the auxiliary burner when the incandescent burner is accidentally put out of use.

Having thus fully described my invention,

Too

valve to control the opening at the crossing Y of the passages in the key, a casing attached to the end of the hollow key, having an open 10 side, a lighting-pipe in said open casing communicating with the longitudinal key-passage, and burner-jets extending upward from the lightingepipe out of the casing to the burner, substantially as described.

In testimony whereof I alfix my signature in 5 presence of two witnesses.
